Willing to sell individually, but this could be a good option for somebody thinking of going last minute, who wants to take a friend or two and sit together for the day (no ticket swapping needed, no hassle)...

Right, sorry to mess everyone around! Vue have actually just given a full refund for all the day tickets, not even an admin fee or anything to pay. Apparently they can do this due to the high demand.

Rather than just deleting this post, I thought it might be helpful for people to know that if they're trying to shift tickets at this stage - it looks like you can get refunds, so you don't necessarily need to find buyers on this forum or elsewhere.
